Abstract: A composition and process for making the composition by co-refining: fibrillated virgin cellulose fibers, waste/recycle cellulose fibers, or both; co-refined cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3 and the weight percent of CE staple fibers is less than 30 wt. %, based on the weight of CE staple fibers and said cellulose fibers; and water. The composition can be co-refined to obtain lower Canadian standard freeness yet improved drainage and wet laid products having good tensile strength, air permeability, stiffness, burst strength, and bulk.

Abstract: A bale of sheets made of waste/recycle cellulose fibers and cellulose ester (CE) staple fibers can be fed to a hydropulper. The CE staple fibers have: i. a denier per filament (DPF) of less than 3, or ii. a cut length of less than 6 mm, or iii. crimping, or iv. a combination of any two or more of (i)-(iii). The bales can be fed and dropped in as entire bales to a hydropulper, or a blend tank directly or indirectly in fluid communication with a hydropulper, using the same feed system employed for feeding cellulose to the hydopulper and avoiding having to defiberize by pulling or drawing fibers from a box container into a hydropulper. The waste/recycle cellulose fibers and CE staple fibers can be co-refined prior to making the bale of sheets.

Abstract: Containers and lids made from cellulose fibers and cellulose ester fibers are provided that have enhanced air permeability, stiffness, R-heat insulation values, or thickness at equivalent grammage basis weights are provided, or alternatively, maintaining one or more of these properties while lowering the basis weight of the containers or lids. The container and lids with this synthetic fiber can be biodegradable when made with cellulose ester fibers having a degree of substitution of not more than 2.5. Examples of such containers are food packaging such as hot or cold delivery boxes.

Abstract: After cellulose fibers and cellulose ester fibers are co-refined, they are fed to a blend tank continuously feeds a wet laid process. The composition in the blend tank includes co-refined cellulose fibers and cellulose ester fibers and one or more additives, and the cellulose ester fibers have a denier per filament (DPF) of less than 3, a cut length of less than 6 mm, crimped, or non-round with a DPF of less than 3.

Abstract: The biocomponent fiber functions as a carrier or vehicle for delivering additives to a polymer composition. The bicomponent fiber may be “splittable segmented pie” or “island-in-the-sea” construction with the sea being the low melt temperature component and the island being the high melt temperature component. The low melt temperature polymer may be selected from the group consisting of low density polyethylene (LDPE), high density polyethylene (HDPE), polylactic acid (PLA), polyhydroxyalkenoate (PHA), polypropylene (PP), polystyrene (PS), polyvinylidene fluoride, polybutylene succinate (PBS), low melt temperature polyethylene terephthalate, polytrimethylene terephthalate (PTT) and low melt temperature nylons.

Abstract: A versatile binder comprising at least one or more sulfopolyesters is provided. These sulfopolyester binders can enhance the dry tensile strength, wet tensile strength, tear force, and burst strength of the nonwoven articles in which they are incorporated. Additionally, the water permeability of these binders can be modified as desired by blending different types of sulfopolyesters to produce the binder. Therefore, the binder can be used in a wide array of nonwoven end products and can be modified accordingly based on the desired properties sought in the nonwoven products.
